Question

Select the output $Y$ of the combination of gates shown in figure for inputs $A=1,B=0;A=1,B=1$ and $A=0,B=0$ respectively.

• A. $(0,1,1)$
• B. $(1,0,1)$
• C. $(1,1,1)$
• D. $(1,0,0)$

Answer 1

Answer: (D)

$(1,0,0)$

Each gate in the above circuit is a NAND gate which gives output as 0 only when both the inputs are 1 while gives 0 in rest of the cases.

Truth table of the circuit is shown above which implies that option D is correct.
